FIELD: chemistry.
SUBSTANCE: invention relates to a rubber composition based on butadiene-nitrile rubber for making industrial rubber articles operated at low temperatures and oil media. Disclosed is a rubber composition based on butadiene-nitrile rubber BNKS-18 AMN, containing the following in pts. wt.: ground sulphur 1.9–2.3, sulphenamide C 0.9–1.1, altax 0.9–1.2, dibutyl sebacate 29.0–32.0, zinc white 4.5–6.5, stearic acid 1.2–1.5, acetonanil N 1.9–2.1, furnace technical carbon N220 32.0–55.0, and technical carbon T900 5.0–30.0.
EFFECT: obtaining rubber with high tensile strength, relative elongation at break and low temperature limit of brittleness.
